.This invention relates; toimprovements in a f structural frame forV supporting bearings .-and more. particularly it relates to asupportingframe Construction. 'for the' supporting rollers and-their bearings f for rotary -kiln's andthe like. j Y

Y' An object of the. invention, is to provide a ,Structural frame adapted to withstandy the Aenormous yvertical pressure ofthe Ykiln shell` in addition to the weight of they rollers and their-bearings,'and to withstand the enormous lateral thrust 'imparted by the rotatingY kiln'to the thrust' rollers.

, 4The invention consists in the features,

combination and arrangement of parts hereinafter described-and. particularly pointed outr in the claims. r Inv the drawings', Figure l shows thev entire-assembly in-, '-cluding the structural steel framev carrying the: rollers and theirfbearings and showing the tireof the kiln shell in Contact with the 1.0..

.Referringto the drawings' 22represents the heavy rolled steelgirders which are securely tied together by means of channel 'bars 23 and I-beamv 24 forminga very strong support for the -four bearings. v.The entire structure is adapted to be embedded inconcrete so' that the upper flange ofthe girder is not subjectedv to any stresses whichmight deflect it, vas the load isl taken by the'concrete. The embedding also prevents shift-ing ofthe frame on the foundation.

Thegirders 22 are tied together at each oftheir ends by a pair of spaced channel bars 23, the flanges 23a of which are disposed downwardly to be embedded in the concrete k'to prevent any longitudinal shifting ofk the frame induced by the motion of the rotating kiln shell. The channel webs arey riveted to the girder flanges as shown at 23h. v Where noy thrust rollers are to be sup- `pro-videdwith an Ifbeam 24 tyingtheigird--` ers togethen at their mid-points.

The frame in a'dditionrto its novelconstruction of girders-Vchannels.andlbeain is: provided with bearing adjustingor locking screw device 25.

to receive a set-screw 28b whichset' screw is adapted to engage the bearing box. Flanges 28 are provided on the plug 28 which are adapted to rest upon the top flange of the girder. Steel castings or brackets such as shown at 30 in Fig. 6 are riveted to the webt of the girder to form pockets 30a to slidably receive the prongs '32 of the plug 28 and toY prevent undue movement of the plug and hold it steady.V

By means of the plug and set screw the bearingmay be adjusted to and retained in the desired position. The plug with the vscrew may be removed by lifting the lug out as soon as the pressure is relieved. en thel plug is removed it is possible to slide l uiolile lon legrol with (he l'iezlring linx il.
